Every conversion, grouped by what you are starting from
ImageConvert.tools reads 11 image formats and writes 9. Pick the format you have, then the one you need. Every conversion below runs on your own device: nothing is uploaded, there is no file size limit, and there is no watermark on the result.
From PNG
PNG is lossless and universally readable, so converting away from it is usually about size or about a specific destination: a smaller JPG or WebP for the web, an ICO for a favicon, a PDF for a document. Nothing about the pixels forces the move.
From JPG
JPG is already lossy, which shapes every conversion out of it: no target format can recover detail the JPEG encoder discarded. Converting to a lossless format stops further loss but does not undo the first pass, and converting to another lossy format compresses the picture a second time.
From JFIF
JFIF files are ordinary JPEG data with an unusual extension that Windows and Chrome occasionally write. Nothing about the image needs fixing; the extension is what confuses software. Converting produces a file with a name the rest of the world recognises.
From WebP
WebP is what a browser hands you when you save an image from a modern website, which is why so many people meet it by accident. Browsers all read it; a lot of desktop software, office documents, print workflows and upload forms still do not. Converting out of WebP is nearly always a compatibility fix rather than a quality decision.
From AVIF
AVIF is the newest of the web formats and the smallest at a given quality, which is exactly why sites serve it and why the file you downloaded will not open. Support outside browsers is still thin, so converting to an older raster format is the practical route into image editors and older tools.
From GIF
GIF is capped at 256 colours, so photographs stored as GIF have already lost colour depth that no conversion brings back. For flat graphics and icons the palette is rarely the constraint, and moving to PNG or WebP usually gives a smaller file at identical quality.
From BMP
BMP stores raw pixels with essentially no compression, so the files are enormous and almost anything else is smaller. Because BMP is lossless, converting to PNG or TIFF costs nothing at all in quality; converting to JPG or WebP trades some detail for a far smaller file.
From TIFF
TIFF is the format scanners, print shops and archives hand you, and no browser will display it. Converting is usually the fastest way to get a scan or a print file into something you can email, upload or put on a web page.
From ICO
ICO is a container that can hold several icon sizes at once. Converting out of it extracts an image you can actually view and edit, though only one size comes out, and a lot of ordinary image viewers will not open the original at all.
From SVG
SVG is vector: shapes and paths rather than pixels, sharp at any size. Converting rasterises it, which fixes the many marketplaces, documents and upload forms that only accept pixel images, but fixes the result at one resolution in the process.
From HEIC
HEIC is what an iPhone saves by default, and it is the single most converted format on the web for one reason: outside Apple's own software, support is patchy. Windows wants a codec extension, plenty of upload forms reject the extension outright, and older editors do not recognise it at all. Converting is usually about getting a file someone else's computer will open, not about quality.
What cannot be converted, and why
Three of the formats on this page are read-only here. HEIC, SVG and JFIF go in but do not come out, and the reasons are worth knowing rather than guessing at.
- No HEIC output. Browsers can be made to decode HEIC, but none of them expose an HEVC image encoder to a web page, and HEVC is patent encumbered. There is no honest way to offer HEIC as a target here, so it is not offered.
- No SVG output. SVG is vector. Turning a photograph into shapes and paths is a tracing problem with no correct answer, not a conversion, so a converter that claims to do it is claiming something it cannot deliver.
- No JFIF output. JFIF is JPEG data under a different extension. Writing a JPG file is the same thing and the resulting file works in more places, so JPG is what comes out.
A conversion that is not possible gets a 404 rather than a page that pretends. See how the conversion actually works for what happens to your pixels, your EXIF data and your transparency along the way.
Only some of these pages are in Google
Every pair above works as a converter. Not every pair is submitted for indexing: a page earns that by having something specific to say about that particular conversion, and 35 of the 91 currently do. The rest are marked noindex and are reachable only from this hub and from each other, which is the honest arrangement: the tool is complete, the writing is not yet.
